CNC router bits and carbide cutting tools with tutorials and technical guides

2-flute Carbide DeepReach High Aspect-ratio Down-cut End-mills (MD204) - 1/4 in. (0.250 in.) shank

Think & Tinker 2-flute downcut end-mills feature an off-center plunging tip style and a high-rake flute profile. They are primarily designed for sheet goods where lifting, de-lamination and splintering must be avoided. Typically, downcut tools should not be used for blind pocketing and work best over spoil boards with pre-formatted vacuum channels.

Manufactured in the USA, every tool is:

  • 100% measured / optically inspected to insure that EVERY tool meets, or exceeds, our published specifications
  • available with depth rings precisely positioned to ±0.0015 in. (0.038mm), virtually eliminating the need for resetting Z-axis zero between tool changes (with bits of same overall length)
  • made from premium grade submicrograin tungsten carbide (HRa 92, HRc 80)

This attention to detail and the use of top quality materials result in tools with dependable cutting characteristics and one of the longest tool lives in the market. Combined with comprehensive customer support, our cutters have become the tools of choice for sign makers, model makers, artists and instrument builders around the world.
